/**
|

|
|
* Creates a function which is a composition of the passed asynchronous
|
||
|
|
* functions. Each function consumes the return value of the function that
|
||
|
|
* follows. Composing functions `f()`, `g()`, and `h()` would produce the result
|
||
|
|
* of `f(g(h()))`, only this version uses callbacks to obtain the return values.
|
||
|
|
*
|
||
|
|
* Each function is executed with the `this` binding of the composed function.
